We thank all the individuals who volunteered for the Fruit and Vegetable Study. Terrence Strawder and Bridgette Collado assisted with study recruitment and data collection. Dr. Joel Heidelbaugh and the staff at the Ypsilanti Family Health Center facilitated recruitment. This study was supported by a grant from the University of Michigan Medical School Clinical Initiatives program. The study utilized the Chemistry Core of the Michigan Diabetes Research and Training Center which is funded by grant DK020572 from the National Institute of Diabetes and Digestive and Kidney Diseases , the General Clinical Research Center (funded by grant M01-RR000042 from the National Center for Research Resources (NCRR) , a component of the NIH) and the University of Michigan Comprehensive Cancer Center Support grant P30-CA46592 .

N2 - Objective: This study examined the feasibility of eliciting dietary changes in subjects recruited from a diverse primary care setting in Michigan using a written, one-page plan, either alone or with telephone counseling. Methods: A total of 96 subjects were enrolled from 9/28/06 to 5/7/07 (49% minorities). Subjects were randomized into three groups. Group 1 received written materials. Group 2 received written materials plus a one-page form that asked them to make a specific daily plan for substituting one less nutritious food with two servings of fruits and vegetables. Group 3 received the written materials, the one-page form and telephone counseling from a dietitian. Results: Subject retention was 76% for the 12-week study. Subjects in Groups 1, 2 and 3 changed their mean intakes of fruit and vegetables by 0.4, -0.7 and 1.4 servings/day, respectively. Participants in Group 3 lost an average of 0.73. kg, increased their perception of the importance of eating fruits and vegetables, and 63% increased their serum levels of carotenoids by 20% or more. Conclusion: Recruitment through a primary care clinic was effective. Formulation of a written plan combined with telephone counseling appears to be promising for improving fruit and vegetable intakes and warrants more definitive study.
